Bret Michaels Suffers Setback, Rep Says

Bret Michaels' recovery has hit a setback, according to his rep. Test results show Michaels is suffering from a lack of sodium, a known side effect of brain hemorrhages that can lead to seizures.

Despite the setback, the Poison singer and Celebrity Apprentice contestant is still in "positive spirits," according to his rep. "He is responding well to tests and treatments," the statement read. "Even though today was a minor setback, doctors remain hopeful for a full recovery and plan to release more specific information next Monday."

Bret Michaels in critical condition after suffering brain hemorrhage

As of Tuesday, Michaels, 47,  was in critical but stable condition and was under close surveillance in the ICU of an undisclosed hospital to prevent any complications from his Type 1 diabetes.

In the same statement, Michaels' rep acknowledged increased speculation that his health problems may be related to the head injury he suffered last June, when he was hit by a prop onstage at the 2009 Tony Awards, and said doctors have planned additional studies to figure out what caused the brain hemorrhage.

Report: Bret Michaels to undergo surgery

"Doctors state Michaels is very lucky as his condition could have been fatal," the statement read. "With further testing and rehabilitation, they are hopeful that Bret will gradually improve as the blood surrounding the brain dissolves and is reabsorbed into his system, which can be a very painful recovery and take several weeks to months."

Earlier on Tuesday, Entertainment Tonight reported Michaels was to undergo surgery due to his deteriorating condition. His father, Wally Sycack, told Extra his son was talking and moving his arms and legs. "He sounded a little slow, but fine. He was talking, not as cheerful as he usually is," Sychak, told Extra. "But he understood what he was saying and knew me. Everything seemed good that way."
